8 Claims.

This invention relates to a motor vehicle fan especially designed for effecting a proper ventilation or stirring of the atmosphere about the occupants thereof, the fan being primarily designed I for use in the passenger compartment of close cars.

On warm days, and especially when the motor vehicle has come to a stop for any reason whatsoever, the heat within the car is very noticeable, and more especially when there is no breeze stirring from the outside. Again, during the summer months when the atmosphere is quite humid, and especially during a heavy shower, the windows or panels of the vehicle become more or less steamed or have a vapor condensed on the glass, by reason of the fact that the atmosphere within the car is not being stirred or properly ventilated.

The primary object of this invention is to pro- 20 vide a motor vehicle fan which may be installed so as to fan the air into the faces of the passengers, or to create a breeze about them for effectively cooling them. A further object of the invention is to provide a motor vehicle fan having a fluid pressure motor operative on a low pressure such as that induced in the intake manifold of the internal combustion engine of such motor vehicle.

Another object of the invention is to provide a fluid pressure motor of the suction operated type which will not only stir air within the vehicle, but will also remove the air to a certain extent so as to effect a more or less continuous changing of the atmosphere within the passenger compartment.

The invention further resides in the mounting of the fan whereby it may be disposed in an outof-the-way position up against the ceiling of the car when the fan is not in use.

Referring more in detail to drawings, the type of motor shown in Fig. l is of the oscillatory, fluid pressure or suction operated type, and comprising a casing 1 which is adapted to be secured to the ceiling of the car 2, a piston or vane 3 arranged within the casing 1, a shaft 4 journaled in the casing and having the piston or vane fixed thereto, and an automatic valve mechanism for alternately connecting the opposite ends of the casing, or the casing on the opposite sides of the piston, to a source of operating pressure. The casing is provided with a suction passage 5 which is connected by a tube 6 to the intake manifold 7 of the engine (not shown), and this passage 5 has a main control valve 8 which may be manually operated to open or close communication between the motor and the manifold. Said passage 5 is provided with two branch conduits 9, each leading to a valve chamber 10, from which latter communication is obtained with the piston chamber to the respective sides of the pisthe accompanying has communication to the atmosphere through a passage 12, which is adapted to be closed by a spring seated valve 13 which carries a valve 14 for closing the suction passage 9 when the valve 13 is unseated. Thus the valve device 13, 14, a1- ternately opens its side of the casing, first to the source of suction or low pressure, and then to the atmosphere. The means for operating the two valves consists of a rocker 15 having oppositely extending arms 16 underlying the stems 17 of the valves 13. This rocker also embodies an upwardly extending bifurcated arm 18 which straddles the shaft 4 and is adapted to have its opposing fureations alternately engaged by a pin 19 fixed to a kicker plate 20, said kicker plate being pivoted on the shaft 4. A spring 21 connects a lateral pin 22 on the rocker member 15 to a lateral pin 23 on the'kicker member 20 so that the resulting action will be to effect a quick movement of the kicker member 20 after the pin passes a dead center position. An actuating member 24 is fixed on the shaft 4 to rock therewith, and as it rocks, said actuator will engage the pin 19 and start the movement of the kicker toward a position in which the pin 23 will be aligned with the pin 22 and the shaft 4, and asthe pin 23 moves beyond this alignment, or dead center position, the potential energy of the tensioned spring 21 will quickly act to continue swingingthe kicker 20 and bring its pin 19 against the opposite furcation 18 to rock the member 15 and thereby reverse the position of the two sets of valves 13 and 14 so that one valve 13 will be seated while the other valve 13 is unseated, and a reverse relation of the valves 14. As the rocker member is rocked, one of its arms 16 is alternately movedv past a retaining projection on a leaf spring 25 which acts to yieldably lock the rocker in both of its positions. This valve actuation will alternately connect the two passages 11 to the source of suction, and the unconnected pas sage 11 will be in communication with the atmosphere, whereby the piston will be oscillated back and forth and effect a rocking of the shaft 4. On the lower end of shaft 4 is mounted a fan of the leaf type, the same comprising a plurality of leaves 26 pivotally connected to the shaft whereby the leaves may be opened or closed, the construction herein shown embodying a pivot bolt 27 about which the leaves pivot and a clamping nut 28 which may be adjusted to secure the leaves 26 at a desired adjustment. The full-line showing of Figs. 1 and 2 illustrates the fan element in this operative position, the angle of which may be varied, and when it is desired to discontinue the use of the fan, the leaves may be folded or collapsed and moved to an out-of-theway position such as is indicated by the dot and dash showing in Fig. 2. The fan is shown disposed in advance of the rear seat and may be folded or swung, to one side to permit a ready entrance or exit from the car.

- pant or occupants of the front seat as well as those of the rear seat.

In Fig. 14 is shown another arrangement of fans which are disposed near the ceiling .of the the motor.

. ton 3 bya conduit 11. This valve chamber also car and to the rear of the back seat, the fans in this instance being of the rotary type and comprising a fan element 29 fixed to a shaft 30 of a rotor or bladed piston 31. This rotor is disposed within a casing 32 from which the air is exhausted th-rough a conduit '33,, which is in turn connected to the intakeImanifold;v valve 34 being inserted in the conduit 33 to control the fan operation. On the opposite side of the casing 32 from which the air is exhausted is a nozzle 35 which is designed to direct an inflowing current of air against the blades of the rotor so that in this modification the atmosphere from within the carwill' also be exhausted through In Figs. 16 and 17 are shown ventilating fans similar to those depicted in Figs. 14 and 15 with the exception'thatthey are reversed and designed to pull or force the air from within the car out through openings 36 provided in the walls of the vehicle. A similar type of rotary motor is employed to drive "thisfan, which maybe supported from the ceiling or the vehicle wall, by suitable brackets 37. In the modifications shown in Figs. 1417, a more or less steady breeze is generated about the passengers so as to effect a constant agitation of the atmosphere' and a continuous renewing of the same bythe exhaustion through the operating fan-motor.

What is claimed as new is:

1. A motor vehicle 'fan for closed cars, com-' prising in combination with the closed passenger compartment of a motor vehicle, a fan element arranged thereinfor'eifecting a change of atmosphere about the occupants, a suction operated, fluid pressure motor arranged within the passenger compartment'for operating the fan element and having its 4 inlet opening into said passenger compartment, and a suction passage between the motor andthe internal combustion engine of the motor vehicle for'having a low pressure induced therein by said engine whereby the atmosphere from within the passenger compartment will be drawn through said motor and effect an operation of the same.

2. A fluid pressure operatedfan for the passenger compartment of a motor vehicle, comprising a fan element, a suction operated motor having a shaft directly supporting the fan element for agitating the air thereabout; and suction inducing means connected to the motor for operating the same, said motor opening to the atmosphere within the passenger compartment whereby the agitated air therein will be in part withdrawn therefrom throughthe motor by said 130 suction inducing means and thereby gradually eifect a change of air in the passenger compartment. 1

3. In a fan construction for the passenger compartment of motor vehicles, a fan element, a fluid pressure, motor foroperating the fan element to agitate the air in the compartment, and means for directing a part of the air within the compartment through the motor to actuate the same whereby the air within the compartment will be both agitated by the fan element and exhausted by the motor to effect a change in the atmosphere.
